The cool thing about the Piltdown Mann's Crook't Stick and the Marcott/Shakun elevator shaft is the obviousness of the deceptive statistics. It's as blatant as the deceit of the public by the authors, and closely intertwined in motive and execution.

They told lies, and the lies lie like bones in the desert, exposed, dessicated, revelatory.=======================

de secco is where desiccate originates, hence one 's' and two 'c's. I have dried up nuts to prove it, and had a bit of an argument with Word Perfect about 25 years ago! Some Spell Checkers still knead learning proper.

This continuous assumption that anyone who does not agree with your delusion is dishonest becomes wearying after a while.Apr 18, 2016 at 10:06 PM Entropic man

Well, EM, if it were an assumption, I'd agree that it might seem tiresome. But when you look at the reality it's clearly not an "assumption".

From the NSF press release:

But when you combine data from sites around the world, you can average out those regional anomalies and get a clear sense of the Earth's global temperature history.

What that history shows, the researchers say, is that during the last 5,000 years, the Earth on average cooled about 1.3 degrees Fahrenheit--until the last 100 years, when it warmed about 1.3 degrees F.

From their subsequent statement on an obscure website (after, for example, the Met Office posted the 'research shows unprecedented warming' headline on their Myclimate website - subsequently removed):

Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions.

Not dishonest? If you say so, EM. If you say so.

My delusion? If not being convinced by what some people say is a delusion, fair enough. But only in the sense that not being convinced by what the God botherers who come to the door tell me is also a delusion.

So either Martin A believes the 1.3F rise did not happen or Marcott et al were lying when they wrote 'Our primary conclusions are based on a comparison of the longer term paleotemperature changes from our reconstruction with the well-documented temperature changes that have occurred over the last century, as documented by the instrumental record.'

Or he could just be wrong, of course. But it is a bit rude to start flinging around accusations of dishonesty before you're sure of the facts.

Heh, gc, of course it looks wrong, now. I'm in the habit of ignoring spellchecker because usually, when I misspell, it's deliberate. Not this time, and if it's any explanation or excuse, I usually misspell that one, unless I think about it.=================

Marcott's and Mann's sticks both have the same basic flaw; they smooth the more distant past to make the recent past seem exceptional. These were lies, and they were deliberate lies. Try to get that through your head; Nature will eventually force it through, but 'twere better for you if you'd smooth the path.======================

As Tamino says 'Look at the spike at the end. The big, and most importantly the steep, scary spike at the end. That’s not an artifact of the way proxy ages were computed, or how the reconstruction was done, or the effect of proxy drop-out as records become more sparse in the later period. It’s what the thermometers say. '

And how many thermometers were in use for most of the past 5,000 years? Oh, dear. None whatsoever, beyond 400 years ago! Do you not find it strange that the uptick starts about the same time that thermometers were put to use? Personally, I would call that too much of coincidence to be ignored; if you recall the “Hide the decline” fiasco, the proxies were continued to the present… can you guess which way the reconstructed temperatures went? And you still bang the drum for the hockey-stick. Oh, boy…
